Quantum Suicide and Immortality

There's a scientific theory in quantum mechanics about suicide and immortality. Easy summary: You can not die because as soon as you die that time line no longer exists for you. You continue life from the place of another version of yourself. This makes you essentially immortal, because even if you die you won't know it. You will continue on a different branch of reality where you survived. It is near impossible to prove for obvious reasons, but if it were true, do you think suicide would be an effective problem solver? Let's say your car breaks down. In the wise words of Frank King, "I have three choices: Get it fixed, get a new one, or I could just kill myself. I know, doesn’t that sound absurd? But that thought actually pops into my head… It’s always on the menu.” Now let's say that you do choose suicide. Immediately you have solved your problem (likely replacing it with new ones, but those can probably be solved the same way).
